Introduction

A varistor is a device with voltage-current characteristics that allow current to surge rapidly under certain voltage conditions. The role of a varistor is to protect electronic components in circuits from overvoltage. Due to its ability to absorb abnormal voltage and current pulses, a varistor can protect electronic devices with very high efficiency.

Features

• Comply with RoHS 2.0, REACH, halogen-free available.
• Standard type 85℃ to 125℃ derating factor: 2.5%/℃
• Varistor voltage temperature coefficient: 0 to -0.05 %/℃ max.
• Storage temperature range: -55℃~+125℃
• Isolation voltage: 2500V 60s (body insulation)

Applications

• Consumer electronics: TVs, audio output devices, safety sockets, set-top boxes, etc.
• Industrial products: motors, semiconductor components, relays, electromagnetic switches, power circuits, three-phase rectifier circuits, automatic control circuits, etc.
• Communications equipment: telephones, fax machines, switches, etc.
